Answer:
x=−7/5and y=−6/5
Step-by-step explanation:
Step: Substitute−2x−4foryiny=3x+3:
y=3x+3
−2x−4=3x+3
−2x−4+−3x=3x+3+−3x(Add -3x to both sides)
−5x−4=3
−5x−4+4=3+4(Add 4 to both sides)
−5x=7
−5x
−5
=
7
−5
(Divide both sides by -5)
x=−7/5
Answer:
i will do it
Step-by-step explanation:
I'm assuming you mean negative integers and mixed. -3--3=? When to negatives are back to back it turns in to a positive number. The equation becomes -3+3=0.
Adding 2 negative numbers will always result in a negative value. -3+-3=-6.
A negative times a negative is always a positive . -2x-2=4
A positive integer times a negative integer will be a negative value. -3x4=-12.
A negative divided by a negative is a negative. -12/-2=-6
A positive divided by a negative is a negative. 9/-3=-3
Answer:
x=31
Step-by-step explanation:
4+ sqrt (x+5) = 10
Subtract 4 from each side
4 -4+ sqrt (x+5) = 10-4
sqrt(x+5) = 6
Square each side
(sqrt(x+5))^2 = 6^2
x+5 = 36
Subtract 5 from each side
x+5-5 = 36-5
x = 31
